KVP
Kilovolt Peak, monitors that we set to control how far the range is.
Scatter Radiation
Scatter of radiation after contact with a mass.
Contrast
Difference between 2 adjacent densities
Spatial Resolution
The detail or clearness of the image.
Computed Radiography
Cassette-based digital radiography, put on plates to produce image. “Old School”
Brightness
Function of a display monitor, changes image lightness/darkness.
Photon
Quantum/ particle of radiant energy.
Remnant Radiation
Area between patient and IR.
CR
Central Ray
SID
Source-Image-Distance. Area between X-ray and patient.
mAs
Milliampere-seconds. Measurement used to control exposure time in seconds.
Radiopaque
Not easily penetrable by X-ray
Inverse Square Law
Math formula that describes the relationship between radiation intensity and source to image distance.
Penetration
Ability of passage through an object controlled by kVp
Primary Radiation
Process of the tube to the patient.
